FIG. 1.

Photographs and terahertz images of samples A–D. The first column shows photographs of the samples, with the cancer areas marked by red lines. The second and the third columns show maps of the absorbance and the refractive index at , respectively, in the same scale as the photographs. The absorbance is shown in color, from 0 to 2.0 for samples A, B, and D, and from 0 to 0.7 for sample C. The value of the refractive index is shown in color from 1.0 to 1.7 for all samples.

FIG. 2.

Score plots with the first (PC1) and the second (PC2) PCs. Each column shows the result of PCA relative to the absorbance spectra, to the refractive index spectra, and to both. The pixels of the cancer tumor are shown in red.

FIG. 3.

Results of the analysis by -means clustering (with crosses marking the initial points) and by hierarchical clustering (Ward’s algorithm with the square of Pearson’s distance).
